Experiments are performed to use a brand of Chinese filter paper in paper chromatographic analysis. The paper used is the "fine" grade filter paper manufactured by the First Eastern Factory, Fou-Shun. It appears that the filter paper, after adequate treatment, may be used in paper chromatographic work. Treatment essentially consists of washing with dilute hydrochloric acid and distilled water and ascending with suitable solvents of the particular cation-groups. In this experiment, the solvents used for chromatographic analysis of aluminium, silver and arsenic groups were modified from that used by F. H. Burstall and others. The results are summarized as follows:Group I R_f: K 0.45, Na 0.56, Mg 0.71Group Ⅱ R_f: Ba 0.45, Sr 0.53, Ca 0.61Group Ⅲa R_f: Al 0.02, Zn 0.73Group Ⅲb R_f: Fe 0.99, Co 0.44, Mn 0.30, Ni 0.00Group Ⅳa R_f: Ag 0.16, Pb 0.00, Hg 0.80Group Ⅳb R_f: Pb 0.02, Cu 0.30, Bi 0.67, Cd 0.82, Hg 0.90Group V R_f: As 0.79, Sb 0.93, Sn 0.95Besides, we have found a number of common reagents which can be used to develop the cations on such kind of filter paper. After chromatographic separation, their sensitivity is determined. The R_f of both the ascending and descending processes has very close values. When temperature varies within 5°C, the R_f values change very little.
